Hi, PR: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95961 In the test case for PR95961, vectorization factor computed by vect_determine_vectorization_factor is [8,8]. But this is updated to [1,1] later by vect_update_vf_for_slp. When we call vect_get_num_vectors in vect_enhance_data_refs_alignment, the number of scalars which is based on the vectorization factor is not a multiple of the the number of elements in the vector type. This leads to the ICE. We should check that before calling vect_get_num_vectors and set local variable 'possible_npeel_number' to zero if there are too few scalars.
Bootstrapped and tested on aarch64-linux-gnu. ChangeLog update are contained in the patch. Comments? Thanks, Felix
